BRAKE-BEAM STRUT.

Specification of Letters Patent.

Patented Feb. 22, 1910.

To all whom it may concern:

Be it known that I, EDWIN Gr. BUSSE, a citizen of the United States,residing at Chicago, Illinois, have invented a certain new and usefulImprovement in Brake- Beam Struts, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure 1 is a section taken through the center of a reversibleadjustable strut of my improved construction. Fig. 2 is a section takenon the line 2-2 of Fig. 1. Fig. 3 is a horizontal section taken on theline 83 of Fig. 1. Fig. 4: is a perspective view of one of theadjustable pin bearing blocks made use of in my improved strut.

My invention relates to an improved brake beam strut, particularlydesigned to permit the use of said strut in either right or left handbeams, and also to permit of the adjustment of the brake lever pin holeto different positions as may be required.

The object of my invention is to provide a simple, inexpensive strut,the main body portion of which may be readily shifted to any angle so asto accommodate the brake levers of right and left hand beams, and saidstrut being provided with a pair of adjustable blocks provided with pinholes which receive the pin on which the brake lever is fulcrumed. Theadjustable pin hole principle of my invention may, with slightmodifications, be advantageously used in connection with struts on theso-called solid beams, or in struts which do not have the reversiblefeature.

To the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts hereinafter more fullydescribed and claimed.

As shown in the drawing, the main body of my improved strut comprises apair of side walls 1, provided with longitudinal slots 2, and formedintegral with the top and bottom edges of said side walls are inwardlyprojecting flanges 8, in the under sides of which are formed teeth 4.Formed integral with the ends of the side walls 1 are end plates 5, andformed integral therewith are tubular studs 6, one of which is swiveledin a sleeve 7, which embraces the central portion of the compressionmember of the brake beam, and the opposite tubular stud being swiveledin a block 8 which engages the central portion of the tension member ofthe beam. The adjustable pin bearing blocks 9 are designed to fitagainst the inner faces of the side walls 1 of the body of the strut,and formed integral with the top and bottom edges of said blocks aretransversely disposed teeth 10 which are adapted to interlock with theteeth 4:. Formed through the centers of the blocks 9 are apertures 11which receive the pin 12 which serves as a fulcrum for the brake lever13. Flanges 14 are formed integral with the inner faces of the blocks 9,which flanges provide bearing faces for the sides of brake lever 13. Byswiveling the tubular studs 6 on the ends of the strut in the sleeve 7and block 8, the main body portion of said strut can readily be shiftedfrom one angle to another, thus accommodating the brake lever at anyangle, and this transforms the beam on which the strut is used from aright hand to a left hand beam, or vice versa. The blocks 9 can bereadily shifted from one end of the body of the strut to the other byremoving the pin 12, and thus the brake lever can be fulcrumed atdifferent points on the strut to suit difierent requirements. The slots2 in the sides of the body of the strut accommodate the pin 12 in itsadjusted positions, and the interlocking teeth 4: and 10 provide meanswhereby the blocks 9 are rigidly maintained in their adjusted positions.

A strut of my improved construction is comparatively simple, comprises aminimum number of parts, is strong and durable, is adapted for use onright or left hand beams, and also provides for an adjustment of thefulcrum of the brake lever.

It will be readily understood that minor changes can be made in. theconstruction and form of my improved strut, without departing from thespirit of my invention.

I claim:

1. The combination with a brake beam strut or lever post, of a pair ofmovable blocks thereon, which blocks are adapted to receive the brakelever pivot pin.

2. The combination with a brake beam strut or lever post, of a pair ofmovable blocks therein, which blocks are adapted to receive the brakelever pivot pin, and means whereby said blocks are locked in adjustedpositions.

3. A brake beam strut or lever post provided with a pair of adjustablebrake lever pivot pin blocks.
